Professional Applications & Engineering Value

This M16 flat washer made from glass-filled nylon plastic addresses common industrial challenges like corrosion, weight, and electrical isolation. Its white color and high-temperature resistance up to 220°F make it suitable for automotive, electrical enclosures, and food processing equipment where metal washers may fail due to rust or conductivity issues. The UL 94 HB rating ensures flame retardancy in wiring applications, while the metric dimensions (17x30mm) provide accurate seating for M16 fasteners, distributing loads evenly and preventing surface damage. Engineers benefit from reduced maintenance costs and enhanced reliability in demanding environments, thanks to its non-magnetic and chemical-resistant properties.

Specification Summary & Compliance

This flat washer conforms to metric system standards with precise inner diameter (17mm) and outer diameter (30mm) for M16 screw compatibility. It meets UL 94 HB flammability specifications and is manufactured from glass-filled nylon with Rockwell M111 hardness for consistent performance. The product is fully compliant with RoHS 3 (2015/863/EU) and REACH (EC 1907/2006) regulations, ensuring adherence to environmental and safety guidelines for industrial components.
